本発明は、粘着部材およびそれを用いた電子機器に関する。  The present invention relates to an adhesive member and an electronic device using the same.

昨今、ノートブック型のパーソナルコンピュータ（ノート型ＰＣ）、タブレット型のパーソナルコンピュータ（タブレット型ＰＣ）、スマートフォンおよび携帯電話等の各種の電子機器はますます薄型化・軽量化が進んでいる。これら電子機器では、筐体内部における液晶ディスプレイ（ＬＣＤ）の周囲にカメラや無線ＬＡＮ用のアンテナを配置しているが、最近ではＷｉＧｉｇ（Wireless Gigabit）等、伝送速度の高速なアンテナを配置したものも登場している。  In recent years, various electronic devices such as notebook personal computers (notebook PCs), tablet personal computers (tablet PCs), smartphones, and mobile phones are becoming thinner and lighter. In these electronic devices, an antenna for a camera or a wireless LAN is arranged around a liquid crystal display (LCD) inside the housing. Recently, an antenna having a high transmission speed such as WiGig (Wireless Gigabit) is arranged. Has also appeared.

特開２００２−３４１７７０号公報JP 2002-341770 A

ここで、上記ＷｉＧｉｇ等の高速通信用のアンテナは発熱量が大きいため、ＬＣＤの周囲に配置した際に、ＣＰＵ等にも使用されているサーマルラバー（Thermal rubber）をその表面に貼り付けて熱を逃がす対策が必要となる。  Here, since the antenna for high-speed communication such as the WiGig generates a large amount of heat, a thermal rubber (Thermal rubber) used also for the CPU or the like is attached to the surface of the antenna when it is placed around the LCD. Measures to escape are necessary.

サーマルラバーは、貼り付け前の状態では、例えばその両面にフィルム状の剥離体（剥離紙）が設けられており、貼り付け時にピンセット等で剥離体を剥離して対象物に貼り付ける。しかしながら、サーマルラバーは、例えば導電性シリコン樹脂等の柔軟な素材で構成されており、かつ剥離体が設けられる両面が粘着面となっている。  The thermal rubber is provided with, for example, a film-like release body (release paper) on both surfaces thereof before being attached, and the attached release object is peeled off with tweezers or the like when attached. However, the thermal rubber is made of a flexible material such as a conductive silicon resin, for example, and both surfaces on which the release body is provided are adhesive surfaces.

そのため、例えば作業者が一方の面の剥離体をピンセット等でつまんで剥離しようとすると、その剥離体を剥離する方向にサーマルラバーが変形して剥離体が使用不可能になってしまう場合や、あるいはサーマルラバーの変形につられて反対側の面に設けられた剥離体が意図せずに剥離してしまう場合があった。すなわち、サーマルラバーの両面に剥離体が設けられている場合に、意図する側の剥離体を剥離すること（剥離紙を剥離する側の制御）が困難であった。  Therefore, for example, when an operator tries to peel the peeled body on one side with tweezers, the thermal rubber is deformed in the direction of peeling the peeled body, and the peeled body becomes unusable, Or the peeling body provided in the surface of the other side with the deformation | transformation of a thermal rubber may peeled unintentionally. That is, when the release bodies are provided on both sides of the thermal rubber, it is difficult to release the release body on the intended side (control of the side to release the release paper).

なお、例えば特許文献１には、剥離体（剥離シート）の剥離性を向上させた粘着記録紙に関する技術が提案されている。しかしながら、同文献で提案された技術は、剥離体が片面のみに設けられている場合に適用可能であり、上記のように剥離体が両面に設けられている場合に意図する側の剥離体を剥離することは困難であった。  For example, Patent Document 1 proposes a technique related to an adhesive recording paper in which the peelability of a release body (release sheet) is improved. However, the technique proposed in this document is applicable when the peeler is provided only on one side, and the peeler on the intended side when the peeler is provided on both sides as described above. It was difficult to peel off.

As shown in FIG. 2, theadhesive member body 10 is disposed (attached) on the surface of theWiGig antenna 56 disposed around thedisplay device 51 and used as a heat radiating member.

［粘着部材の構成］
以下、本発明の実施形態に係る粘着部材１の詳細について説明する。粘着部材１は、図３〜図５に示すように、粘着部材本体１０と、第１剥離体２と、第２剥離体３と、を備えている。[Configuration of adhesive member]
Hereinafter, the detail of the adhesion member 1 which concerns on embodiment of this invention is demonstrated. As shown in FIGS. 3 to 5, the adhesive member 1 includes anadhesive member body 10, afirst release body 2, and a second release body 3.

粘着部材本体１０は、例えば放熱用のサーマルラバーであり、基材となるシリコン樹脂に導電性微粒子を混合させた導電性シリコン樹脂から構成される。粘着部材本体１０は、図４に示すように、両面に粘着面１１ａ，１１ｂを有し、薄いシート状に形成されている。粘着部材本体１０は、同図に示すように、図３をＸ１−Ｘ１方向で切断した断面形状が平行四辺形で形成され、図５に示すように、図３をＸ２−Ｘ２方向で切断した断面形状が矩形で形成されている。  The adhesive membermain body 10 is, for example, a thermal rubber for heat dissipation, and is made of a conductive silicon resin obtained by mixing conductive fine particles with a silicon resin as a base material. As shown in FIG. 4, the adhesive membermain body 10 hasadhesive surfaces 11a and 11b on both sides, and is formed in a thin sheet shape. As shown in FIG. 5, the adhesive membermain body 10 is formed by a parallelogram in a cross-sectional shape obtained by cutting FIG. 3 in the X1-X1 direction, and as shown in FIG. 5, the cross-sectional shape is cut in the X2-X2 direction. The cross-sectional shape is a rectangle.

粘着部材本体１０の長手方向における２つの端面１２ａ，１２ｂは、図４に示すように、粘着部材本体１０の粘着面１１ａ，１１ｂに対して、直角以外の角度で傾斜している。すなわち、粘着部材本体１０の一方の端面（第１の端面）１２ａは、粘着部材本体１０の一方の粘着面１１ａとの間で鋭角θ_１を形成しているとともに、粘着部材本体１０の他方の粘着面１１ｂとの間で鈍角θ_２を形成している。また、粘着部材本体１０の他方の端面（第２の端面）１２ｂは、粘着部材本体１０の一方の粘着面１１ａとの間で鈍角θ_２を形成しているとともに、粘着部材本体１０の他方の粘着面１１ｂとの間で鋭角θ_１を形成している。As shown in FIG. 4, the twoend surfaces 12 a and 12 b in the longitudinal direction of the adhesive membermain body 10 are inclined with respect to theadhesive surfaces 11 a and 11 b of the adhesive membermain body 10 at an angle other than a right angle. That is, one end surface (first end surface) 12a of the adhesive membermain body 10 forms an acute angle θ1 with the_oneadhesive surface 11a of the adhesive membermain body 10, and the other end of the adhesive membermain body 10 forming an obtuse angle theta₂ between theadhesive surface 11b. The other end surface (second end surface) 12b of theadhesive member body 10, together form an obtuse angle theta₂ between the one of theadhesive surface 11a of theadhesive member body 10, the otheradhesive member body 10 forming an acute angle theta₁ between theadhesive surface 11b.

ここで、粘着部材本体１０の長手方向における２つの端面１２ａ，１２ｂにおける鋭角θ_１および鈍角θ_２の角度は特に限定されないが、例えば鈍角θ_２を１００度以上（鋭角θ_１を８０度以下）とすることが好ましく、鈍角θ_２を１３５度（鋭角θ_１を４５度）とすることがより好ましい。これにより、後記するように第１剥離体２および第２剥離体３を粘着部材本体１０から容易に剥離することができる。なお、図４では、端面１２ａ側の鋭角および鈍角と、端面１２ｂ側の鋭角および鈍角とを同じ記号（θ_１，θ_２）で示しているが、両者の角度はそれぞれ異なっていても構わない。Here, the angles of the acute angle θ₁ and the obtuse angle θ₂ at the two end faces 12a and 12b in the longitudinal direction of the adhesive membermain body 10 are not particularly limited. For example, the obtuse angle θ₂ is 100 degrees or more (the acute angle θ₁ is 80 degrees or less). It is preferable that the obtuse angle θ₂ is 135 degrees (the acute angle θ₁ is 45 degrees). Thereby, the1st peeling body 2 and the 2nd peeling body 3 can be easily peeled from the adhesion membermain body 10 so that it may mention later. In FIG. 4, the acute angle and obtuse angle on theend face 12a side and the acute angle and obtuse angle on theend face 12b side are indicated by the same symbol (θ₁ , θ₂ ), but the angles may be different from each other. .

粘着部材本体１０の短手方向における２つの端面１３ａ，１３ｂは、図５に示すように、上記端面１２ａ，１２ｂとは異なり、粘着部材本体１０の粘着面１１ａ，１１ｂに対して、直角に形成されている。なお、粘着部材本体１０は、例えばトムソン型やビク型の金型を用いた打ち抜き加工によって形成することができる。また、前記したように粘着部材本体１０の端面１２ａ，１２ｂを傾斜させるには、例えば粘着部材本体１０を構成する材料を金型の動きに合わせて移動させながら打ち抜き加工を行えばよい。  As shown in FIG. 5, the two end faces 13a and 13b in the short direction of the adhesive membermain body 10 are formed at right angles to the adhesive faces 11a and 11b of the adhesive membermain body 10, unlike the end faces 12a and 12b. Has been. The adhesive membermain body 10 can be formed by punching using, for example, a Thomson or Bic mold. Further, as described above, in order to incline the end faces 12a and 12b of the adhesive membermain body 10, for example, a punching process may be performed while moving the material constituting the adhesive membermain body 10 in accordance with the movement of the mold.

第１剥離体２および第２剥離体３は、作業者が粘着部材本体１０を電子機器５の内部機器（例えばＷｉＧｉｇ用アンテナ５６）に貼り付ける際の利便性の観点から設けられるものであり、例えば樹脂からなる薄い剥離フィルムや、剥離紙等から構成される。第１剥離体２および第２剥離体３は、図４に示すように、粘着面１１ａおよび粘着面１１ｂにそれぞれ配置されている。また、第１剥離体２および第２剥離体３は、粘着面１１ａ，１１ｂに対応する被粘着面２１，３１に、例えば離型剤がコーティングされている。  Thefirst peeler 2 and the second peeler 3 are provided from the viewpoint of convenience when an operator attaches theadhesive member body 10 to an internal device of the electronic device 5 (for example, the WiGig antenna 56). For example, it is composed of a thin release film made of resin, release paper or the like. As shown in FIG. 4, the1st peeling body 2 and the 2nd peeling body 3 are each arrange | positioned at theadhesion surface 11a and theadhesion surface 11b. Moreover, as for the1st peeling body 2 and the 2nd peeling body 3, the to-be-adhered surfaces 21 and 31 corresponding to the adhesion surfaces 11a and 11b are coated with the mold release agent, for example.

第１剥離体２および第２剥離体３は、図４に示すように、粘着部材本体１０の長手方向において、粘着部材本体１０の端面１２ａ，１２ｂで鈍角θ_２が形成された側が、粘着部材本体１０の端面１２ａ，１２ｂから突出するように配置されている。すなわち、第１剥離体２は、端面１２ｂの鈍角θ_２側が長手方向に長さｌ_２だけ突出した突出部２２ｂを有している。また、第２剥離体３は、端面１２ａの鈍角θ_２側が長手方向に長さｌ_２だけ突出した突出部３２ｂを有している。As shown in FIG. 4, the first peeledbody 2 and the second peeled body 3 are such that the side where the obtuse angle θ₂ is formed on the end surfaces 12 a and 12 b of the pressure sensitive adhesive membermain body 10 is the pressure sensitive adhesive member in the longitudinal direction of the pressure sensitive adhesive membermain body 10.

That is, the first strippingmember 2 has a projectingportion 22b obtuse theta₂ side of theend face 12b protrudes by a length l₂ in the longitudinal direction. The second stripping member 3 has aprotrusion 32b which obtuse angle theta₂ side of theend face 12a protrudes by a length l₂ in the longitudinal direction.

このような構成を備えることにより、突出部２２ｂを把持して粘着面１１ａから離間する方向に力を加えることにより、第２剥離体３を粘着部材本体１０から剥離させることなく、第１剥離体２のみを粘着部材本体１０から容易に剥離することができる（後記図７参照）。また、突出部３２ｂを把持して粘着面１１ｂから離間する方向に力を加えることにより、第１剥離体２を粘着部材本体１０から剥離させることなく、第２剥離体３のみを粘着部材本体１０から容易に剥離することができる。なお、図４では、突出部２２ｂの長さと、突出部３２ｂの長さとを同じ記号（ｌ_２）で示しているが、両者の長さはそれぞれ異なっていても構わない。また、第１剥離体２と第２剥離体３のいずれか一方にだけ突出部２２ｂあるいは突出部３２ｂを設けるようにしてもよい。By providing such a configuration, the first peeling body can be held without peeling the second peeling body 3 from the adhesive membermain body 10 by gripping theprotrusion 22b and applying a force in a direction away from theadhesive surface 11a. Only 2 can be easily peeled from the adhesive member main body 10 (see FIG. 7 described later). In addition, by gripping theprotrusion 32b and applying a force in a direction away from theadhesive surface 11b, only the second peeled body 3 is removed from the adhesive membermain body 10 without peeling the first peeledbody 2 from the adhesive membermain body 10.

ここで、第１剥離体２および第２剥離体３は、粘着部材本体１０の端面１２ａ，１２ｂにおいて鋭角θ_１が形成された側から突出する長さｌ_１と、粘着部材本体１０の端面１２ａ，１２ｂにおいて鈍角θ_２が形成された側から突出する長さｌ_２とが異なる。すなわち、第１剥離体２および第２剥離体３は、突出部２２ａ，３２ａの長さｌ_１が突出部２２ｂ，３２ｂの長さｌ_２よりも長くなるように構成されている。The first strippingmember 2 and the second release member 3, the adhesivemember end face 12a of thebody 10, the length_{l 1} that projects from the side of the acute angle theta₁ is formed at 12b, theend face 12a of theadhesive member body 10 12b is different from the length l₂ protruding from the side where the obtuse angle θ₂ is formed. That is, the first strippingmember 2 and the second release member 3, the protrudingportion 22a, the length_{l 1} of 32a is configured to be longer than theprotrusion 22b, 32 b of the length_{l 2.}

このような構成を備えることにより、作業者が粘着部材１の粘着部材本体１０を電子機器５の内部機器に配置する際に、突出部２２ａ，３２ａと突出部２２ｂ，３２ｂの長さの違いにより、鋭角θ_１側と鈍角θ_２側とを容易に判別することが可能となる。なお、図４では、突出部２２ａ，３２ａの長さｌ_１が突出部２２ｂ，３２ｂの長さｌ_２よりも長くなるように構成されているが、例えば突出部２２ａ，３２ａの長さｌ_１が突出部２２ｂ，３２ｂの長さｌ_２よりも短くなるように構成しても構わない。By providing such a configuration, when the operator places the adhesive membermain body 10 of the adhesive member 1 in the internal device of theelectronic device 5, due to the difference in length between the protrudingportions 22 a and 32 a and the protrudingportions 22 b and 32 b. Thus, it is possible to easily discriminate between the acute angle θ₁ side and the obtuse angle θ₂ side. In FIG. 4, the length l₁ of theprotrusions 22 a and 32 a is configured to be longer than the length l₂ of theprotrusions 22 b and 32 b. For example, the length l₁ of theprotrusions 22 a and 32 a is used. but it may be configured to be shorter than the protrudingportion 22b, 32 b of the length l_2.

また、第１剥離体２および第２剥離体３は、粘着部材本体１０の端面１２ａ，１２ｂにおいて鋭角θ_１が形成された側と、粘着部材本体１０の端面１２ａ，１２ｂにおいて鈍角θ_２が形成された側とで異なる形態を有するようにしてもよい。例えば、鋭角θ_１が形成された側と鈍角θ_２が形成された側とで、第１剥離体２および第２剥離体３の端面や表面の色、模様または形状を変えることができる。このようにすることで、第１剥離体２および第２剥離体３において鋭角θ_１が形成された側と鈍角θ_２が形成された側とを、見た目や感触で容易に判別できるようになる。第１剥離体２および第２剥離体３は、突出部２２ａ，２２ｂ，３２ａ，３２ｂそれぞれの有無に関わらず、このような形態の変化を持たせることができる。Moreover, the1st peeling body 2 and the 2nd peeling body 3 form the obtuse angle (theta)₂ in theend surface 12a, 12b of the adhesive membermain body 10 in which the acute angle (theta)₁ was formed, and the end surfaces 12a, 12b of the adhesive membermain body 10. You may make it have a different form by the side made. For example, it is possible to vary the acute angle theta₁ is formed in the side and obtuse theta₂ formed side, the color of the end surface and the surface of thefirst separating member 2 and the second release member 3, a pattern or shape. By doing in this way, in the1st peeling body 2 and the 2nd peeling body 3, the side in which the acute angle (theta)₁ was formed, and the side in which the obtuse angle (theta)₂ was formed can be easily discriminate | determined now by appearance and a touch. . The firstpeelable body 2 and the second peelable body 3 can have such a change in form regardless of the presence or absence of theprotrusions 22a, 22b, 32a, and 32b.

第１剥離体２および第２剥離体３は、図５に示すように、粘着部材本体１０の短手方向において、上記長手方向の場合とは異なり、粘着部材本体１０の端面１３ａ，１３ｂから突出しておらず、粘着部材本体１０と同じ長さ（幅）で構成されている。  As shown in FIG. 5, thefirst peeler 2 and the second peeler 3 protrude from the end faces 13 a and 13 b of theadhesive member body 10 in the short direction of theadhesive member body 10, unlike the case of the longitudinal direction. However, it is configured with the same length (width) as the adhesive membermain body 10.

なお、第１剥離体２および第２剥離体３は、粘着部材本体１０を例えばトムソン型やビク型の金型を用いて打ち抜き加工して図４および図５に示すような形状に成形した後で、粘着面１１ａ，１１ｂの両面に設けられる。  In addition, the1st peeling body 2 and the 2nd peeling body 3 are after forming the adhesive membermain body 10 into the shape as shown in FIG.4 and FIG.5 by stamping using the Thomson type | mold or BIC type | mold metal mold | die, for example And provided on both surfaces of theadhesive surfaces 11a and 11b.

［粘着部材の貼付手順］
以下、本実施形態に係る粘着部材１の粘着部材本体１０を、電子機器５の内部機器であるＷｉＧｉｇ用アンテナ５６に貼り付ける手順（貼付方法）について説明する。以下では、粘着部材本体１０の両面に設けられた第１剥離体２および第２剥離体３をそれぞれ把持部材（ピンセット）Ｐで把持して剥離し、粘着部材本体１０をＷｉＧｉｇ用アンテナ５６に貼り付ける例について説明する。[Attachment procedure of adhesive material]
Hereinafter, a procedure (sticking method) for sticking the adhesive membermain body 10 of the adhesive member 1 according to the present embodiment to theWiGig antenna 56 that is an internal device of theelectronic device 5 will be described. Hereinafter, thefirst peeling body 2 and the second peeling body 3 provided on both surfaces of the adhesive membermain body 10 are respectively held by the gripping members (tweezers) P to be peeled off, and the adhesive membermain body 10 is attached to theWiGig antenna 56. An example of attaching will be described.

まず、粘着部材本体１０から第２剥離体３を剥離する。この場合、図６に示すように、第２剥離体３を作業者の手指等により支持した状態（図示省略）で、把持部材Ｐによって第１剥離体２の突出部２２ａを把持して持ち上げる。すると、同図に示すように、第１剥離体２の被粘着面２１と粘着部材本体１０の粘着面１１ａとが密着して貼り付いた状態で、粘着部材本体１０の粘着面１１ｂと第２剥離体３の被粘着面３１とが徐々に離間し、最終的には粘着部材本体１０から第２剥離体３が剥離される。そして、第１剥離体２に貼り付いた状態の粘着部材本体１０をＷｉＧｉｇ用アンテナ５６の表面に載置し、把持部材Ｐによる把持を解除する（図示省略）。  First, the 2nd peeling body 3 is peeled from the adhesion membermain body 10. FIG. In this case, as shown in FIG. 6, the protrudingportion 22 a of thefirst peeling body 2 is gripped and lifted by the gripping member P in a state where the second peeling body 3 is supported by an operator's fingers or the like (not shown). Then, as shown in the figure, the pressure-sensitive adhesive surface 11b of the pressure-sensitive adhesive membermain body 10 and the second pressure-sensitive adhesive surface 21b of the pressure-sensitive adhesive membermain body 10 are attached in a state where the pressure-sensitive adhesive surface 21 of the first peeledbody 2 and the pressure-sensitiveadhesive surface 11a of the pressure-sensitive adhesive membermain body 10 are adhered. The peeled body 3 is gradually separated from theadherend surface 31, and finally the second peeled body 3 is peeled from the adhesive membermain body 10. Then, the pressure-sensitive adhesive membermain body 10 attached to thefirst peeling body 2 is placed on the surface of theWiGig antenna 56, and the gripping by the gripping member P is released (not shown).

このように、本実施形態に係る粘着部材１は、粘着部材本体１０の両面に第１剥離体２および第２剥離体３がそれぞれ配置された状態において、図６に示すように、第１剥離体２の突出部２２ａ，２２ｂのうち、粘着部材本体１０の鋭角θ_１側にある突出部２２ａを把持して持ち上げることにより、粘着部材本体１０から第２剥離体３のみを確実に剥離することができる。As described above, the pressure-sensitive adhesive member 1 according to the present embodiment has the first peel-off as shown in FIG.protrusion 22a of thebody 2, of 22b, by lifting grips the projectingportion 22a located at an acute angle theta₁ side of the pressure-sensitive member body 10, to be reliably peeled off only the second stripping member 3 from the pressure-sensitiveadhesive member body 10 Can do.

一方、図６とは反対に、例えば第１剥離体２の突出部２２ａ，２２ｂのうち、粘着部材本体１０の鈍角θ_２側にある突出部２２ｂを把持して持ち上げた場合、粘着部材本体１０から第１剥離体２のみを確実に剥離することができる。すなわち、本実施形態に係る粘着部材１は、持ち上げる突出部（突出部２２ａまたは突出部２２ｂ）に応じて、剥離する剥離体（第１剥離体２または第２剥離体３）を選択することができる。その原理については後記する（図９〜図１２参照）。On the other hand, as opposed to FIG. 6, when, for example, first separatingmember 2 of theprojection 22a, among 22b, lifted by gripping the projectingportion 22b on the obtuse angle theta₂ side of theadhesive member body 10, theadhesive member body 10 Therefore, only the first peeledbody 2 can be peeled reliably. That is, the pressure-sensitive adhesive member 1 according to the present embodiment can select a peeling body (thefirst peeling body 2 or the second peeling body 3) to be peeled according to the protruding portion (the protrudingportion 22a or the protrudingportion 22b) to be lifted. it can. The principle will be described later (see FIGS. 9 to 12).

続いて、粘着部材本体１０から第１剥離体２を剥離する。この場合、図７に示すように、把持部材Ｐによって、図６で把持した突出部２２ａとは逆側の突出部２２ｂを把持して持ち上げる。すると、同図に示すように、粘着部材本体１０の粘着面１１ｂとＷｉＧｉｇ用アンテナ５６の表面とが貼り付いた状態で、粘着部材本体１０の粘着面１１ａと第１剥離体２の被粘着面２１とが徐々に離間し、最終的には粘着部材本体１０から第１剥離体２が剥離される。これにより、ＷｉＧｉｇ用アンテナ５６の表面に対する粘着部材本体１０の配置が完了する。  Then, the1st peeling body 2 is peeled from the adhesive membermain body 10. FIG. In this case, as shown in FIG. 7, the gripping member P grips and lifts theprotrusion 22b opposite to theprotrusion 22a gripped in FIG. Then, as shown in the figure, theadhesive surface 11a of theadhesive member body 10 and the adherend surface of the first peeledbody 2 in a state where theadhesive surface 11b of theadhesive member body 10 and the surface of theWiGig antenna 56 are attached. 21 is gradually separated, and finally, thefirst peeling body 2 is peeled from the adhesive membermain body 10. Thereby, arrangement | positioning of the adhesion membermain body 10 with respect to the surface of theantenna 56 for WiGig is completed.

なお、図６において、例えば第１剥離体２に貼り付いた状態の粘着部材本体１０をＷｉＧｉｇ用アンテナ５６の表面に載置した際に、載置予定位置からずれてしまった場合、図８に示すように、把持部材Ｐによって第１剥離体２の突出部２２ａを把持して持ち上げる。すると、同図に示すように、第１剥離体２の被粘着面２１と粘着部材本体１０の粘着面１１ａとが密着して貼り付いた状態で、粘着部材本体１０の粘着面１１ｂとＷｉＧｉｇ用アンテナ５６の表面とが徐々に離間し、最終的にはＷｉＧｉｇ用アンテナ５６の表面から粘着部材本体１０が剥離される。これにより、粘着部材本体１０をＷｉＧｉｇ用アンテナ５６の表面における載置予定位置に再度貼り直すことができる。  In FIG. 6, for example, when the adhesive membermain body 10 attached to thefirst peeling body 2 is placed on the surface of theWiGig antenna 56, the position is shifted from the intended placement position in FIG. 8. As shown, the gripping member P grips and lifts theprotrusion 22a of thefirst peeler 2. Then, as shown in the figure, the pressure-sensitive adhesive surface 11b of the pressure-sensitive adhesive membermain body 10 and the WiGig for WiGig in a state where the pressure-sensitive adhesive surface 21 of the first peeledbody 2 and the pressure-sensitiveadhesive surface 11a of the pressure-sensitive adhesive membermain body 10 are adhered and adhered. The surface of theantenna 56 is gradually separated from the surface, and finally, the adhesive membermain body 10 is peeled from the surface of theWiGig antenna 56. Thereby, the adhesive membermain body 10 can be affixed again on the planned placement position on the surface of theWiGig antenna 56.

［剥離体の剥離の原理］
以下、第１剥離体２および第２剥離体３の剥離の原理について、従来技術と本発明の実施形態との比較を交えて説明する。なお、以下の説明で参照する図９〜図１２では、粘着部材１，１０１の片側半分のみを図示し、残り半分の図示を省略する。[Principle of exfoliation]
Hereinafter, the principle of peeling of the first peeledbody 2 and the second peeled body 3 will be described with a comparison between the prior art and the embodiment of the present invention. 9 to 12 referred to in the following description, only one half of theadhesive members 1 and 101 is shown, and the other half is not shown.

従来技術に係る粘着部材１０１は、例えば図９に示すように、粘着部材本体１１０の長手方向における端面１１２ａが、粘着部材本体１１０の粘着面１１ａ，１１ｂに対して直角に形成されている。そのため、粘着部材本体１１０の端面１１２ａ近傍において、粘着部材本体１１０の強度（粘着部材本体１１０の厚み方向に働く力に対する強度）が一定となる。  For example, as shown in FIG. 9, the pressure-sensitive adhesive member 101 according to the related art has anend surface 112 a in the longitudinal direction of the pressure-sensitive adhesive membermain body 110 formed at right angles to the pressure-sensitive adhesive surfaces 11 a and 11 b of the pressure-sensitive adhesive membermain body 110. Therefore, in the vicinity of theend surface 112a of the adhesive membermain body 110, the strength of the adhesive member main body 110 (strength against the force acting in the thickness direction of the adhesive member main body 110) is constant.

従って、従来技術に係る粘着部材１０１は、図１０に示すように、作業者が突出部２２ａを持ち上げた際に、第１剥離体２と第２剥離体３のどちらが剥離するのか、言い換えると、粘着部材本体１１０が第１剥離体２と第２剥離体３のどちらに追従するかが分からず、作業者の意図通りに第１剥離体２または第２剥離体３を剥離することが困難である。  Therefore, theadhesive member 101 according to the related art, as shown in FIG. 10, when the operator lifts the protrudingportion 22a, which of the first peeledbody 2 and the second peeled body 3 is peeled, in other words, It is difficult to know whether the adhesive membermain body 110 follows thefirst peeler 2 or the second peeler 3, and it is difficult to peel thefirst peeler 2 or the second peeler 3 as intended by the operator. is there.

一方、本実施形態に係る粘着部材１は、図１１に示すように、粘着部材本体１０の長手方向における端面１２ａが、粘着部材本体１０の粘着面１１ａ，１１ｂに対して直角以外の角度に傾斜している。そのため、粘着部材本体１０の端面１２ａ近傍において、粘着部材本体１０の強度（粘着部材本体１０の厚み方向に働く力に対する強度）が一定ではなくなる。すなわち、粘着部材本体１０の端面１２ａ近傍において、鋭角θ_１側の強度が低くなり、鈍角θ_２側の強度が高くなる。On the other hand, as shown in FIG. 11, in the adhesive member 1 according to the present embodiment, theend surface 12 a in the longitudinal direction of the adhesive membermain body 10 is inclined at an angle other than a right angle with respect to theadhesive surfaces 11 a and 11 b of the adhesive membermain body 10. doing. Therefore, in the vicinity of theend surface 12a of theadhesive member body 10, the strength of the adhesive member body 10 (strength against the force acting in the thickness direction of the adhesive member body 10) is not constant. That is, theend face 12a near theadhesive member body 10, the strength of the acute angle theta₁ side is lowered, the strength of the obtuse angle theta₂ side is higher.

従って、本発明の実施形態に係る粘着部材１は、図１２に示すように、作業者が突出部２２ａを持ち上げた際に、粘着部材本体１０における鋭角θ_１側が鈍角θ_２側よりも先に変形することにより、第１剥離体２の被粘着面２１と粘着部材本体１０の粘着面１１ａとの密着状態が維持される。そして、同図に示すように、粘着部材本体１０が第１剥離体２に追従し、粘着部材本体１０から第２剥離体３が剥離される。Therefore, the adhesive member 1 according to the embodiment of the present invention, as shown in FIG. 12, when the operator lifts the protrudingportion 22a, acute theta₁ side before the obtuse theta₂ side of theadhesive member body 10 By deform | transforming, the contact | adherence state of the to-be-adhered surface 21 of the1st peeling body 2 and theadhesion surface 11a of the adhesion membermain body 10 is maintained. And as shown in the figure, the adhesion membermain body 10 follows the1st peeling body 2, and the 2nd peeling body 3 peels from the adhesion membermain body 10. FIG.

以上のように、本実施形態に係る粘着部材１は、粘着部材本体１０の２つの対向する端面１２ａ，１２ｂが粘着面１１ａ，１１ｂに対して直角以外の角度に傾斜していることにより、粘着部材本体１０の端面１２ａ，１２ｂ近傍における強度を変えることができる。従って、粘着部材本体１０の粘着面１１ａ，１１ｂに設けられる第１剥離体２および第２剥離体３を容易に、かつ作業者の意図通りに剥離することが可能となる。また、粘着部材１は、貼り直しも容易であるため、リワーク性も向上する。  As described above, the pressure-sensitive adhesive member 1 according to the present embodiment has a pressure-sensitiveadhesive member body 10 in which twoopposing end surfaces 12a and 12b are inclined at an angle other than a right angle with respect to the pressure-sensitive surfaces 11a and 11b. The strength in the vicinity of the end faces 12a and 12b of themember body 10 can be changed. Therefore, it becomes possible to peel the1st peeling body 2 and the 2nd peeling body 3 provided in the adhesion surfaces 11a and 11b of the adhesion membermain body 10 easily and as the operator intends. Moreover, since the adhesive member 1 can be easily re-attached, reworkability is also improved.

以上、本発明に係る粘着部材およびそれを用いた電子機器について、発明を実施するための形態により具体的に説明したが、本発明の趣旨はこれらの記載に限定されるものではなく、特許請求の範囲の記載に基づいて広く解釈されなければならない。また、これらの記載に基づいて種々変更、改変等したものも本発明の趣旨に含まれることはいうまでもない。  As described above, the adhesive member according to the present invention and the electronic device using the same have been specifically described by the embodiments for carrying out the invention. However, the gist of the present invention is not limited to these descriptions, and the claims can be made. Should be interpreted broadly based on the description of the scope. Needless to say, various changes and modifications based on these descriptions are also included in the spirit of the present invention.

例えば、図１および図２では、粘着部材１を適用可能な電子機器５としてノート型ＰＣを例示したが、粘着部材１は、その他にもタブレット型ＰＣ、スマートフォンおよび携帯電話等の電子機器５において、放熱が必要な内部機器の表面に配置しても構わない。  For example, in FIG. 1 and FIG. 2, a notebook PC is exemplified as theelectronic device 5 to which the adhesive member 1 can be applied. However, the adhesive member 1 is also used inelectronic devices 5 such as tablet PCs, smartphones, and mobile phones. It may be arranged on the surface of an internal device that requires heat dissipation.

また、図１および図２では、粘着部材１の粘着部材本体１０をＷｉＧｉｇ用アンテナ５６の表面に配置した例について説明したが、電子機器５の内部において、放熱が必要な他の内部機器の表面に配置しても構わない。  1 and 2, the example in which the adhesive membermain body 10 of the adhesive member 1 is arranged on the surface of theWiGig antenna 56 has been described. However, the surface of another internal device that needs to dissipate heat inside theelectronic device 5. You may arrange in.

また、本発明の実施形態に係る粘着部材１では、粘着部材本体１０として放熱用のサーマルラバーを想定していたが、粘着部材本体１０は、例えば電子機器５の内部機器に使用される衝撃吸収ゲルや、フォーム材からなる両面テープ等であっても構わない。  In the pressure-sensitive adhesive member 1 according to the embodiment of the present invention, a thermal rubber for heat dissipation is assumed as the pressure-sensitive adhesive membermain body 10, but the pressure-sensitive adhesive membermain body 10 is, for example, a shock absorber used for an internal device of theelectronic device 5. It may be a gel or a double-sided tape made of a foam material.

また、本発明の実施形態に係る粘着部材１では、粘着部材本体１０の長手方向における２つの端面１２ａ，１２ｂを直角以外の角度で傾斜させ、粘着部材本体１０の短手方向における２つの端面１３ａ，１３ｂを直角に形成していたが、それとは反対に、端面１２ａ，１２ｂを直角に形成し、端面１３ａ，１３ｂを直角以外の角度で傾斜させても構わない。この場合、第１剥離体２および第２剥離体３は、粘着部材本体１０の短手方向において、粘着部材本体１０の端面１３ａ，１３ｂから突出するように形成する。  In the pressure-sensitive adhesive member 1 according to the embodiment of the present invention, the twoend surfaces 12 a and 12 b in the longitudinal direction of the pressure-sensitive adhesive membermain body 10 are inclined at an angle other than a right angle, and the twoend surfaces 13 a in the short direction of the pressure-sensitive adhesive membermain body 10. 13b is formed at a right angle, but on the contrary, the end faces 12a and 12b may be formed at a right angle and the end faces 13a and 13b may be inclined at an angle other than a right angle. In this case, the firstpeelable body 2 and the second peelable body 3 are formed so as to protrude from the end faces 13 a and 13 b of the adhesive membermain body 10 in the short direction of the adhesive membermain body 10.

また、本発明の実施形態に係る粘着部材１では、粘着部材本体１０の断面形状が平行四辺形で形成されていたが、端面１２ａおよび端面１２ｂが、粘着部材本体１０の一方の粘着面（粘着面１１ａまたは粘着面１１ｂ）との間で、それぞれ鋭角θ_１および鈍角θ_２を形成する構成であれば、その他の形状（台形を除く）であっても構わない。Moreover, in the adhesive member 1 which concerns on embodiment of this invention, although the cross-sectional shape of the adhesive membermain body 10 was formed in the parallelogram, theend surface 12a and theend surface 12b are one adhesive surfaces (adhesive) of the adhesive membermain body 10. Any other shape (excluding trapezoid) may be used as long as it forms an acute angle θ₁ and an obtuse angle θ₂ with thesurface 11a or theadhesive surface 11b).
